IMPROVEMENT IN BUTTER-WQRKERS.

Specification forming part ofLetters Patent No. 190,252, dated May 1, 1877; application filed February 3, 1877.

To all whom it may concern:

Be it known that 1, CHARLES A. SANDS, of Burlington, in the county of Coffee and State of Kansas, have invented a new and Improved Fig. 2 is a top view of the same with follower removed.

Similar letters of reference indicate correspondin g parts.

The invention relates to an improved apparatus for working butter, so as to separate the buttermilk, for the purpose of avoiding the greasy condition which most butter obtains by too much handling, while it also cools the butter ready for salting. v The invention consists of a tub with perforated screen, forming with the tub an icechamber and an interior cylinder perforated at the lower part, through which the butter is forced by a screw-follower. The interior cyl' indcr and screen are secured detachably to the tub by a diametrical and encircling bar that enters locking-recesses of the tub.

In the drawing, A represents the tub, and

G a cylindrical perforated screen that forms with the tub an ice-chamber. A diametrical top piece, B, is hinged to one side of the tub and locked at the opposite side by a hinged bail, B. The piece B carries the screw-rod E of the follower E, that is raised or lowered in an interior cylinder, D, by a top hand-wheel, the follower being provided with a packingring to fit'tightly into the cylinder D. The lower part D of the cylinder D is perforated, for the purpose of forcing the butter from the interior through the perforations into the space between screen and cylinder. The screen and cylinder are firmly retained in position by a diametrical bar, F, that is seated in recesses a of the screen and extended around the cylinder, the ends looking into L- shaped recesses b at diametrically-opposite points of the tub.

When the locking-bar is turned in the recesses b it maybe detached from the tub, and

the screen and cylinder taken out of the tub, so that all the parts may be thoroughly cleaned, the follower having been first removed by being screwed up until clearing the cylinder, and being then swung with the top piece to the outside of the tub.

When the tub is used'for work it is filled with water, which is cooledby the ice placed between screen and tub. The cold water rises to the same level in the interior cylinder as in the outer screen, the butter being placed into the cylinder and forced down by the action of the follower, lowered by the hand-wheeliofthe screw-shaft.

The butter is forced through the lower perforated part of the cylinder and rises in finelyseparated condition, vermicelli like, through the cold water in the space between the cylinder and screen to the surface of the same,

when the same process may be repeated, it necessary, to separate the buttermilk entirely from the butter, which is at the same time cid and assume the greasy condition in which most butter is sent to market.

Having thus described my invention, I claim as new and desire to secure by Letters. Patent- 1. A butter-worker, consisting of a tub, perforated screen, interior cylinder with lower perforated part, and slidingfollower, the whole constructed and operated substantially as and for the purpose set forth.

2. The combination of the interior cylinder D, recessed screen 0, and tub A, having L- shaped recesses with a detachable lockingbar, F, seated in the recessesof screen and tub, and encircling the inner cylinder, to admit ready taking out and cleaning of parts, substantially as specified.
